Definitions
- the invention relates to a full butt joint structure of a frame side beam connecting joint and a welding process.
- the frame side beam joint structure cannot realize the full butt joint connection.
- Most of the side beam joints are designed as corner joints or corner joints and butt joint structures; individual also have overlapping structures.
- the stress concentration factor of the side beam joints, especially the weld zone is large, which reduces the fatigue life of the frame and affects the load carrying capacity and running speed of the bogie.
- the technical problem to be solved by the present invention is to provide a full docking structure and a welding process of the side frame connecting joint of the steering frame with the least stress concentration in the weld zone, thereby improving the fatigue life of the frame and making the steering frame safer and more reliable.
- the present invention provides a full butt joint structure of a side beam connecting joint of a bogie frame, which is characterized in that: the side beam and the beam are fully butt jointed through the connecting seat, and the side beam connecting end and the side beam inner vertical plate are formed.
- the board-to-board butt joint structure has a beam connecting end and a beam forming a pipe-to-pipe joint structure.
- Steering frame side beam connecting joint full butt structure welding method characterized in that: the connecting seat and the beam tube group welding beam form a group welding joint seat and the side beam groove inner vertical plate and the guide column group side beam reinforcing partition plate and The upper cover group is welded to the entire frame.
- the connecting seat and the beam tube are connected by a robot MAG welding method, and the rest are manually MAG welding methods.
- the connecting seat and the beam tube are cleaned when double-sided welding is used, and the side pad is used for butt welding of the vertical plate.
- the new side beam and beam connecting joint of the invention realizes full butt joint connection between the frame side beam and the beam, and at the same time, the connecting joint is used to avoid the high stress section and the large shape change area, and the welding is performed. In theory, this is the most ideal joint structure, namely: minimum stress concentration at the welded joint, minimum weld filling, minimum welding residual stress and deformation; continuous and beautiful structural shape; strong load carrying capacity and fatigue resistance.
- the invention breaks through the traditional process of synthesizing the frame after the side beam and the beam are finished products, and the advantage is far superior to the angular connection structure or the angular connection and the butt joint structure of the existing structure, and the invention is superior to the overlapping structure.
- the drawing is a schematic view of the full butt joint structure of the side beam connecting joint.
- the side beam and the beam 1 are fully butt jointed by the connecting seat 2, and the side beam connecting end forms a plate-to-board butt joint structure with the side beam inner vertical plate 5 and the guide post 3, and the beam connecting end and the beam form a tube.
- a pipe butt joint structure, 4 is an upper cover, 6 is a lower cover, and 7 is a side beam reinforcement partition.
- the steering frame welding process of the side cross-beam full docking structure When the side beam is a semi-finished product (the side beam groove without the upper cover), the complete frame of the completed frame is the most prominent feature of the new frame welding process.
- the process breaks through the traditional process of synthesizing the frame after the side beam and the beam are finished products, and the process can ensure the automatic MAG welding of the beam tube and the connecting seat; the smooth welding of the side beam reinforcing partition can be realized; Ensure that the beam is assembled with the exact pair of side slabs and high quality welds.
- the joint and the beam tube are welded by the mature robot MAG welding method, and the weld is subjected to RT inspection; the joint and the side beam groove inner vertical plate and the guide column are welded, and the removable gasket is manually MAG welded, and the weld is subjected to UT inspection. , with reliable weld quality assurance.
- the gapless pair is used before the welding of the connecting seat and the beam tube.
- the welding shrinkage amount is accurately unified, and the beam length can be controlled within the range of ⁇ 0.5, and the beam can be guaranteed without secondary processing.
- the composition and the side beam slots complete precise pairing and welding.
